Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

open access: yesThe Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Description of Encephalon Morphology of Nile Tilapia Oreochromis niloticus (Linnaeus, 1758) (Perciformes: Cichlidae) From Brazil

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 1, January 2026.
ABSTRACT The Nile tilapia (Oreochromis niloticus) is a cichlid species native to Africa and is widely farmed in tropical and subtropical regions around the world, making it one of the most commercially important aquaculture species. Despite its significance, there is still a lack of detailed anatomical descriptions of its brain.

Trans‐Synaptic Virus Tracing Reveals Reciprocal Connections of the Interpeduncular Nucleus With the Mood, Exteroceptive, Interoceptive, and Motor Control Systems

open access: yesJournal of Comparative Neurology, Volume 533, Issue 11, November 2025.
The interpeduncular nucleus (IPN) in zebrafish plays a pivotal role in directional decision‐making, social conflict, and fear responses. The anterograde and retrograde connections of the dorsal and intermediate IPN are revealed through the use of monosynaptic and trans‐synaptic viral tracers.

Impaired Proteostasis is Linked to Neurological Pathology in a Zebrafish NGLY1 Deficiency Model

open access: yesJournal of Inherited Metabolic Disease, Volume 48, Issue 4, July 2025.
ABSTRACT NGLY1 is a key enzyme in the process of misfolded protein deglycosylation. Bi‐allelic pathogenic variants in NGLY1 cause N‐glycanase deficiency, also known as congenital disorder of deglycosylation (NGLY1‐CDDG). This rare and multisystem autosomal recessive disorder is linked to a variable phenotype of global developmental delay, neuromuscular

An insect †Archaeopteryx: Cretaceous amber fossil elucidates the evolution of complex host detection and ovipositor mechanisms in parasitoid woodwasps (Hymenoptera: Orussoidea)

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 630-645, July 2025.
We describe †Cretovelona orussopteryx n. gen. & sp. from Kachin amber. The fossil is examined with synchrotron scanning and integrated into an existing morphological data set for Orussoidea. This fossil parasitoid wasp displays a unique character combination demonstrating intermediate conditions in evolving the complex features employed in echo ...

Quantitative Proteomic Analysis of Cardiac Xenograft Failure in a Pig‐to‐Non‐Human Primate Model Identifies NF‐κB as a Critical Immunomodulatory Target

open access: yesXenotransplantation, Volume 32, Issue 3, May/June 2025.
ABSTRACT Introduction Shortage of donor organs is one of the greatest challenges of cardiac transplantation. Xenotransplantation is a potential way to solve the contradiction of imbalance and pigs are considered ideal donor sources. However, xenotransplantation still faces the problem of immune rejection at present.

Transforming growth factor‐β‐mediated regulation of atoh1‐expressing neural progenitors is involved in the generation of cerebellar granule cells in larval and adult zebrafish

open access: yesDevelopment, Growth &Differentiation, Volume 67, Issue 3, Page 149-164, April 2025.
Proliferating neural progenitor cells that generate granule cells are located in the molecular layer (ML) of the cerebellum. Among these, some atoh1c‐expressing cells begin to differentiate and migrate to the granular layer (GL), where they localize as mature granule cells.

Gene expression patterns of the LDL receptor and its inhibitor Pcsk9 in the adult zebrafish brain suggest a possible role in neurogenesis

open access: yesEuropean Journal of Neuroscience, Volume 61, Issue 1, January 2025.
Abstract The low‐density lipoprotein receptor (LDLr) is the first member of a closely related transmembrane protein family. It is known for its involvement in various physiological processes, mainly in the regulation of lipid metabolism, especially in the brains of mammals and zebrafish.

Comprehensive Assessment of Rapeseed Meal as a Fish Meal Substitute in Hybrid Sturgeon (Acipenser schrenckii ♀ × Acipenser baerii ♂) Diets: Impacts on Growth Performance, Body Composition, Immunological Responses, Intestinal Histology, and Inflammatory Response

open access: yesAquaculture Nutrition, Volume 2025, Issue 1, 2025.
This study aimed to assess the impact of incorporating rapeseed meal (RM) as a partial substitute for fish meal (FM) in the diet of cultured hybrid sturgeon (Acipenser schrenckii ♀ × Acipenser baerii ♂). A total of 450 juvenile hybrid sturgeon with similar weights were randomly assigned to five dietary groups, each with triplicates of 30 fish per tank.
